The gameplay loop is addictive and satisfying. It does get a little repetitive after a while, but for something to pick up and play for a few minutes on a bus ride or something it's great. I thought the use of chance/luck was a good interpretation of the theme too.
I liked the color palette chosen a lot. The graphics were also solid. Small gripe, but the inconsistent pixel sizing irked me.
My favorite part was the sound design. I was really vibing with the music in particular. Really groovy and cozy - perfect for a puzzle game.
Nice job!
